Marjorie Jewel "Marlow" Moss (29 May 1889 – 23 August 1958) was the first British Constructivist artist; she worked in painting and sculpture.

[5][10] She was a founding member of the Abstraction-Création association and was the only British artist to feature in all five annuals published by the group.

[11][12] At the beginning of World War II Moss left France to live near Lamorna Cove in Cornwall, studying architecture at the Penzance School of Art.

Then she'd pace up and down again and then – uh, a square would be drawn.Individual exhibitions of her work were staged by Erica Brausen in the Hanover Gallery in London in 1953 and 1958.

Other exhibitions took place in the Stedelijk Museum, Amsterdam, in 1962 and in the Town Hall of Middleburg in Spring 1972.
